In the time that followed the creation of the soil and stone of the continent of Ahlus by Caihrnn, the Lord in the Quiet Places, almighty elemental powers that embodied the primordial forces of nature ravaged his creation. Rolling plains were transformed into valleys with their passage, forests flooded by emerging rivers and lakes, mountain peaks billowed ash and molten rock.

Eventually, these Primordial Princes were banished by the gods of the newly-eventuated Ahlusian Pantheon, and so they remain in slumber upon distant and disparate planes, served by those few that still seek their glory.

The Primordial Elemental Princes

The Primordial Elemental Princes, referred to more generally as the Archomentals, have come to be known by a number of names over the centuries.

• Baylepyre (Fire), whose flames burn searing and bright in perpetuum.
• The Bitter King (Cold), wielder of blizzards that can encase entire cities in ice.
• The Corroded One (Acid), master of a caustic fury that eats through stone, metal and flesh alike.
• The Enlightening Lord (Lightning), the wrath of which flashes bold against the clouds overhead.
• The Stoneheart Despoiler (Bludgeoning), capable of sundering hills and mountains with each stride.
• The Storm Ascendant (Thunder), the rumbling echo that haunts wherever the tempest resides.
• Torrentspate (Bludgeoning), dweller of the crushing weight of the demersal depths.
• The Voice of the Gale (Slashing), caller in the breeze and the squall alike.

Primigenial Presence

Your connection with one of the first entities to reside on the Ahlusian continent augments your body's resilience. At 1st level, your hit point maximum increases by 1, and it increases in this way each time you gain a Warlock level.

In addition, you learn to speak, read and write Primordial.

Archaic Avatar

Beginning at 1st level, you can act as a conduit for your patron's power. As a bonus action on your turn, you can turn yourself into an Archaic Avatar, gaining the following benefits:

• You gain temporary hit points equal to your Warlock level.
• When you make a Strength-based ability check or a Strength saving throw, you gain a bonus equal to your Charisma modifier (minimum of 1).
• When you roll for damage after hitting a target with a melee weapon, you deal additional magical damage corresponding to your patron's damage type equal to your Charisma modifier (minimum of 1).

Archaic Avatar lasts for 1 minute, but ends early if you are incapacitated, if you die, or if you dismiss it as a bonus action. Once you have used this feature, you cannot do so again until you have finished a short or long rest.

Elemental Aegis

From 6th level, you have gained the staying power of your patron. You have a pool of d6s that you can use to mitigate the damage dealt by threats and foes. You have a number of dice equal to your 1 + your proficiency bonus. As a reaction when you take damage, you can roll a number of dice from this pool, reducing the damage taken by an amount equal to your roll + your Charisma modifier. Your pool regains all expended dice when you finish a long rest.

In addition, your Archaic Avatar is further augmented by the primordial power of your patron. While in your Archaic Avatar form, you gain resistance to the damage type with which your patron is most closely associated. 

Resolute Resolve

As your relationship with your patrons deepens further, their magic bolsters your body beyond that of most mundane creatures. Starting at 10th level, when you make a Constitution check or Constitution saving throw, you gain a bonus to your roll equal to your Charisma modifier (minimum of 1).

Remnant of Yore

You have grown so accustomed to the magic of your patron that wielding its full potential is no longer draining on your mortal frame. From 14th level, you now gain immunity to your patron's associated damage type. Warlocks of the Stoneheart Despoiler, the Torrentspate and the Voice of the Gale gain immunity to the nonmagical form of their damage type only, but also gain resistance to another type of nonmagical damage of their choice, choosing from bludgeoning, piercing or slashing damage.

Whilst in your Archaic Avatar form, when you take damage corresponding with your immunity you can choose to instead heal for the amount of damage negated by your immunity. Once you have used this feature, you cannot do so again until you finish a long rest.
